Sooner or later there comes a time… a time when you just got to plug it in and find out if it is going to work. Hence my title “Smoke ’em if you got ’em”. Success, no smoke came out. However,there has been more than one problem.

The hard part of our electronic design is over… Well sort of. We are just moving into a new phase of it, but at least we will not be talking theory. Finally we are actually going to mount parts to something and start thinking about how we will get it

Way back there in November in a post called “Goals of Calibration of the Thermistor Circuit“, I used the diagram to shown in picture 1 to explain how I intended to linearize and calibrate the thermistors. I made one almost fatal mistake…I changed my mind. Seriously, I had intended

The thermistor circuit is complete! There are a few resistor values I want to check before I show all of of the values, but essentially the circuit is complete. This circuit will do everything we described in the last thermistor post, “One More Step Closer to Completing the Thermistor Circuit”. There

What is a model? Without taking the time to look up an official definition, I would say it is a representation of reality. (I am sure some women would like to argue that point with me, but when I wrote the definition, I was not thinking of THAT kind of model!

Tonight is time to zoom out and look at the block diagram of the thermistors. When drawing a CAD drawing it is necessary to sometimes zoom in and work with details and sometimes necessary to zoom out and look at the overview. When designing parts of a process to

We are not to the end of talking about the thermistor yet but we can see the light at the end tunnel. Last night’s post “Principles of linearization” was a long one with lots of math… tonight’s post is relatively short and mostly pictures. I think we

Tonight we are going to take our first steps toward making that scary looking exponential curve of the thermistor resistance into something we can use. The plot show in the first picture is the one we created in “Our First Look at Thermistor details” and was created by simply

Today we are making a slight turn from the analog world into the digital world. Computers are nice when it comes to crunching numbers and recording data, but somehow we have to get those real-world values into the computer. The device that does that is called

We have went through a lot of information about the standard Op-Amp amplifiers so before going on and complicating things even more it is time to summarize what we have learned. To keep things as practical as possible I will do this from the point of view of the
